Description

Technical Field

[0001] The utility model relates to the technical field of mosquito repellent devices, and particularly relates to an electric mosquito repellent liquid device. Background Art

[0002] Mosquito repellent devices are divided into two types: electric heating sheet mosquito repellent devices and electric heating liquid mosquito repellent devices. They both use the constant temperature effect of heating elements to slowly release drugs and volatilize gases to kill and repel mosquitoes. The electric heating liquid mosquito repellent is composed of a mosquito repellent liquid and an electric heater. When the electric heater is connected to the power supply, the PTCR element starts to heat up, and then relies on its own temperature regulation function to keep its temperature within a certain range. The heat generated by the PTCR element is transferred to the liquid medicine volatilization core through heat radiation, so that the liquid medicine sucked from the liquid medicine bottle to the upper end of the core rod by the capillary action of the volatilization core increases the volatilization speed under the heat radiation heating. When the effective insecticidal ingredient in the space reaches a certain concentration, it will have a repelling, paralyzing, knocking down and killing effect on mosquitoes. Existing electric heating liquid mosquito repellents usually only have a power-on indicator light, and the electric mosquito repellent liquid is generally a transparent solution. Users cannot know how much its capacity is without careful observation, and users may forget to turn off the switch when using the electric heating liquid mosquito repellent. Since the working principle of the electric mosquito repellent liquid is heating, when the heating time is too long and the mosquito repellent liquid is used up, it is very easy to cause a fire.

[0003] The prior art, such as the patent with the publication number of "CN103371140A", discloses an electric heating liquid mosquito repellent device with a function of reminding when the liquid medicine is burned dry. The buzzer in it can emit music to remind users to add liquid medicine or cut off the power supply after the mosquito repellent liquid is burned dry. Although the above prior art can achieve the function of emitting music to remind when the mosquito repellent liquid is burned dry, it can only play a reminder role and cannot avoid the situation that the device continues to work after the mosquito repellent liquid is used up. Content of the Utility Model

[0004] The purpose of the utility model is to provide an electric mosquito repellent liquid device to solve the problem that the device continues to work after the electric mosquito repellent liquid is burned dry, which is likely to cause a circuit break and lead to a fire.

[0005] To solve the above technical problems, the utility model provides the following technical solution: an electric mosquito repellent liquid device, including a bottle body, a mosquito repellent liquid contained in the bottle body, a heating rod and a heater. The top end of the heating rod is connected to the heater, and the bottom of the heating rod penetrates through the bottle body and is located in the mosquito repellent liquid. A control component for detecting the resistance value of the mosquito repellent liquid is connected between the inside of the bottle body and the inside of the heater. The control component is also used to control the heater to work. The control component is electrically connected to a relay, and the relay is electrically connected to a warning light.

[0006] Working principle of the utility model: When the electric mosquito repellent liquid device is working, the control component detects the resistance value and controls the change of the warning light to correspond to the capacity state of the electric mosquito repellent liquid. When the mosquito repellent liquid is about to run out, the warning light changes to remind the user to replace the mosquito repellent liquid. When the mosquito repellent liquid is completely exhausted, the control component turns off all the power of the circuit, and the whole system shuts down, stopping heating to prevent dry burning.

[0007] Beneficial effects of the utility model: Utilizing the conductivity of the mosquito repellent liquid, the resistance value between the two ends of the detection control system is detected. As the solution decreases, the resistance value shows an increasing trend. The change of the warning light is controlled according to the detected resistance value, and finally the on-off of the circuit is controlled, avoiding the fire caused by the device short - circuit after the mosquito repellent liquid is burned dry. At the same time, the capacity of the mosquito repellent liquid in the device can be observed at any time according to the change of the warning light.

[0008] Further, the control component includes a single - chip microcomputer system, a first metal sheet and a second metal sheet. The single - chip microcomputer system is electrically connected inside the heater. The first metal sheet is connected between the heating rod and the heater, and the second metal sheet is connected between the inside of the bottle body and the single - chip microcomputer system. One end of the second metal sheet located inside the bottle body is connected to the mosquito repellent liquid, and the first metal sheet and the second metal sheet are in the same circuit. During operation, the single - chip microcomputer system detects the resistance value between the first metal sheet and the second metal sheet.

[0009] Further, the single - chip microcomputer system includes a processor, a radio frequency unit, a power supply, a sensor, a display unit, a storage, a user input unit and an interface unit. The interface unit is used to detect the resistance value of the mosquito repellent liquid, the relay switch and the warning light state control.

[0010] Further, the single - chip microcomputer system also includes a network module, and the network module is used for timing switch and remote control. Through the setting of the network template, the device can achieve timing switch and remote control.

[0011] Further, the warning light is an RGB light. The resistance value of the mosquito repellent liquid is divided into three thresholds: low, medium and high. When the detected resistance value is in the low - threshold range, the RGB light shows blue, indicating that the capacity of the mosquito repellent liquid is sufficient. When the detected resistance value is in the medium - threshold range, the RGB light shows green, indicating that the capacity of the mosquito repellent liquid is medium. When the detected resistance value is in the high - threshold range, the RGB light shows red, indicating that the capacity of the mosquito repellent liquid is too low. When the mosquito repellent liquid is about to run out, the red light flashes alternately. Through the corresponding change of the RGB light and the three resistance values of the mosquito repellent liquid, the capacity of the mosquito repellent liquid can be observed at any time.

[0012] Further, one end of the second metal sheet connected to the electric mosquito repellent liquid is located at the bottom of the bottle body. Through the limitation of the position of the second metal sheet, the single - chip microcomputer can detect the resistance value when the mosquito repellent liquid is completely burned dry.

[0018] The embodiment is basically as shown in the attached Figure 1 - attached Figure 3 shown: An electric mosquito repellent liquid 7 device includes a bottle body 6, a mosquito repellent liquid 7 contained in the bottle body 6, a heating rod 8, a heater 4, a control component, and an RGB lamp 2. The top end of the heating rod 8 is electrically connected to the heater 4, and the bottom of the heating rod 8 penetrates through the bottle body 6 and is located in the mosquito repellent liquid 7. The heater 4 is detachably connected to the top end of the bottle body 6. The control component includes a single-chip microcomputer system 3, a first metal sheet 1, and a second metal sheet 5. The first metal sheet 1 is fixedly connected between the heating rod 8 and the heater 4, and the second metal sheet 5 is fixedly connected between the bottle body 6 and the single-chip microcomputer system 3. The bottom end of the second metal sheet 5 penetrates through the bottom end of the bottle body 6 and contacts the mosquito repellent liquid 7. The first metal sheet 1 and the second metal sheet 5 are located in the same circuit. The single-chip microcomputer system 3 is electrically connected inside the heater 4. The single-chip microcomputer system 3 is electrically connected to a relay, and the relay is electrically connected to an RGB lamp 2. The single-chip microcomputer system 3 includes a processor, a radio frequency unit, a power supply, a sensor, a display unit, a memory, a user input unit, a network module, and an interface unit. The interface unit is used to detect the resistance value of the mosquito repellent liquid 7, the relay switch, and the status control of the RGB lamp 2. The resistance value of the mosquito repellent liquid 7 is divided into three thresholds: low, medium, and high. When the detected resistance value is in the low threshold range, the RGB lamp 2 displays blue, indicating that the capacity of the mosquito repellent liquid 7 is sufficient. When the detected resistance value is in the medium threshold range, the RGB lamp 2 displays green, indicating that the capacity of the mosquito repellent liquid 7 is medium. When the detected resistance value is in the high threshold range, the RGB lamp 2 displays red, indicating that the capacity of the mosquito repellent liquid 7 is too low. When the mosquito repellent liquid 7 is about to be exhausted, the red RGB lamp 2 flashes alternately.

[0019] The specific implementation process is as follows: The device is powered on, and the heater 4 starts to work. The heating rod 8 heats the mosquito repellent liquid 7, and the mosquito repellent liquid 7 volatilizes into the air. At this time, the single-chip microcomputer is turned on, and the single-chip microcomputer detects the resistance value between the first metal sheet 1 and the second metal sheet 5. If the resistance value is not infinite, the relay is powered on, and the working mode of the RGB lamp 2 is selected according to the threshold range where the resistance value is located. When the mosquito repellent liquid 7 is about to run out, the red RGB lamp 2 flashes alternately to remind the user to replace the mosquito repellent liquid 7. When the mosquito repellent liquid 7 is completely exhausted, the detected resistance value is infinite. At this time, the single-chip microcomputer controls the disconnection of the main power supply, the RGB lamp 2 goes out, and the heating stops to prevent dry burning. On this basis, wireless modules such as WiFi, Bluetooth, and zigbee can be added according to the actual situation to realize the timing switch and remote control functions of the mosquito repellent, preventing fire accidents when the user forgets to turn off the electric mosquito repellent and there is no one at home.
